I Learned Something Yesterday

I went to the dentist yesterday and, during a small break when she did not have her fingers in my mouth,  I asked my dental hygienist if she could tell which side of the mouth people chew on by looking at their teeth.  She said no but she could tell if they were left or right handed; you always brush harder on the same side of your body as your dominant hand.   Sherlock Holmes would have loved that observation.
